AVO VOLCANO ACTIVITY NOTIFICATION

ALASKA VOLCANO OBSERVATORY DAILY UPDATE
U.S. Geological Survey
Saturday, November 22, 2014, 11:37 AM AKST (Saturday, November 22, 2014, 20:37 UTC)


PAVLOF VOLCANO (VNUM #312030)
55°25'2" N 161°53'37" W, Summit Elevation 8261 ft (2518 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE

Seismic activity at Pavlof has decreased somewhat over the past day, but is still above background levels. Weakly elevated surface temperatures, consistent with the cooling lava flow on the volcano's northwest flank, were observed in satellite. The eruption has greatly diminished or paused since explosive activity on November 15.

Pauses of days to weeks are common during eruptive episodes at Pavlof and increased activity could occur with little warning.


SHISHALDIN VOLCANO (VNUM #311360)
54°45'19" N 163°58'16" W, Summit Elevation 9373 ft (2857 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE

Seismic activity in the form of intermittent volcanic tremor continues. Overnight, elevated surface temperatures at the summit were detected by satellite, consistent with low-level eruptive activity. The webcam remains obscured by clouds, snow, and rain.

CLEVELAND VOLCANO (VNUM #311240)
52°49'20" N 169°56'42" W, Summit Elevation 5676 ft (1730 m)
Current Volcano Alert Level: ADVISORY
Current Aviation Color Code: YELLOW

Satellite and webcam views obscured by clouds over the past day. Seismicity remains low.

OTHER ALASKA VOLCANOES

Other Alaska volcanoes show no signs of significant unrest: http://www.avo.alaska.edu/activity/

AVO scientists conduct daily checks of earthquake activity at all seismically-monitored volcanoes, examine web camera and satellite images for evidence of airborne ash and elevated surface temperatures, and consult other monitoring data as needed.
